We present the analysis of the gravitational microlensing event OGLE-2013-BLG-0102. The light curve of the event is characterized by a strong short-term anomaly superposed on a smoothly varying ...

In a first-of-its-kind collaboration, NASA’s Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least ...

Through gravitational microlensing, a student from the University of Tasmania has been accepted to work for NASA. Her research will involve exoplanets, their properties, and more. David Menidrey from ...

Researchers have discovered the very first rogue black hole, and it's less than 5,000 light-years away. The astronomers detected and measured the mass of an isolated stellar-mass black hole over the ...

Astronomers have confirmed a Saturn-size world drifting alone in deep space roughly 10,000 light-years from Earth, a discovery that turns a once-theoretical idea into a measured reality. The planet ...

This graphic shows how microlensing was used to measure the mass of a white dwarf star. The dwarf, called LAWD 37, is a burned-out star in the center of this Hubble Space Telescope image. Credits: ...

Astronomers have discovered what may be a free-floating black hole by observing the brightening of a more distant star as its light was distorted by the object's strong gravitational field -- ...

Deep in the constellations of Lyra, there existed an amazing phenomenon disguising itself as an impossible astronomical body. An object resembling the “upside-down planet” that contradicted the laws ...
